Audio split mode

The 540R v3 is able to allow the user to listen to one source whilst viewing another. For instance this can be useful if it is desired to watch a sports channel from say a set-top/satellite video source whilst getting audio commentary from the Radio Tuner. Another example might be to listen to a CD whilst watching a video channel, perhaps waiting for a TV programme to start.

First select the Video channel you wish to watch in the normal way. Now press and hold down the button for the channel you wish to listen to. After 4 seconds approx ‘Audio Split’ will scroll across the display and you will now be listening to the other source.

To cancel audio split mode simply select a new source and normal operation will be resumed.

Bass/Treble configuration

Select the ‘Bass/Treble configuration’ menu:

Bass/Treble Menu

Bass : 0dB

Treble : 0dB

Return to Menu

: [OSD]

The Bass response can be adjusted +/- 10dB @ 100Hz (shelving). The Treble response can be adjusted +/-10dB @ 10kHz (shelving). The ‘Tone’ icon will light up on the display if these controls are adjusted away from 0dB (flat).

Bass/Treble adjustments can also be made from the remote without entering the OSD by pressing the Bass/Treble button and then using the Vol Up/Down buttons.

Subwoofer setup

As covered in the ‘540R v3 Setup’ section the 540R v3 performs bass management for any speaker that is set to ‘Small’ in the OSD. This means that bass for speakers that are unable to reproduce it effectively is instead routed to the subwoofer.

Select the ‘Sub Setup’ menu:

Sub Crossover

The crossover adjustment in the Sub Setup menu is used to determine the point as which this transition is made. In other words it sets the frequency below which bass is routed away from any ‘Small’ speakers and into the Subwoofer channel. It should be understood that bass sent to the subwoofer by bass management is different to bass encoded into the surround-sound material as a dedicated Low Frequency Effects channel. The crossover point can be adjusted from 40Hz to 150Hz in 10Hz steps.

If the source material contains a separate LFE channel (ie DD or DTS material) this is always routed to the subwoofer (if it is On) and is not affected by the crossover setting. Some encoding types (Such as Dolby PLII and Neo:6) do not actually have a LFE channel.

Advanced bass management

The 540R v3 also features an advanced bass management system which when turned on allows the user to set different crossover frequencies for different modes of operation, plus a special Bass Augment function.

To enable advanced bass management highlight the ‘Advanced Sub’ item in the Sub Setup menu and use the Left or Right arrows to turn it on:

Return to Menu

With advanced bass management now on, the ‘Sub Crossover’ item disappears and a new item called ‘Advanced Menu’ appears. To make changes to the advanced settings navigate to ‘Advanced Menu’ and press Enter:

Advanced Sub Menu

Return to Menu

:[OSD]

It is now possible to set three separate crossover points and Trim levels (+/- 10dB) for each of the three main types of operation. DD/DTS decoding, PLII/Neo:6 decoding and Stereo + Sub operation.

Also possible is a Bass Augment function for DD/DTS or PLII/Neo:6 operation.

In normal operation (Bass Augment Off) if the Front speakers are set to ‘Small’ (in the ‘Speaker Config’ menu) their bass is re-directed by high- pass filtering the Fronts and sending that bass to the Sub channel (i.e. bass is removed from the Fronts and sent to the Sub). If they are set to ‘Large’ no filtering takes place and no bass is sent from them to the Sub channel.

However with the Bass Augment function On and the Front speakers set to ‘Large’, bass from the Front Left and Right is now sent to the Sub channel without any filtering of the Front Left and Right taking place (i.e. these channels remain full range). In other words, the bass in the Sub channel is augmented by extra bass from the Front Left and Right channels. If the Front Left and Right are set ‘Small’, Bass Augment has no effect and operation is the same as for Bass Augment Off.

Bass Augment can be On or Off separately for DD/DTS or PLII/Neo:6 operation.

There is no Sub Augment function for Stereo + Sub mode because in this mode if the Front speakers are set to ‘Large’ they will actually always be unfiltered.
